It's interesting, and it looks amusing, but it sadly doesn't approach the old EUII MP games with a dozen+ people. For a similar reason that HOI never really gripped me.
The timeframe is short enough, that there really isn't any thought about consequences, or long-term plans. It leads to everyone thinking only of short-term accommodations and immediate gratification.
The least interesting part of a EUII game, was always the last twenty years, where everyone begin playing only for themselves.
The best times were always in the late 1600s to early 1700s...say from about 1650-1750. Because people were established by then, and if the game was still going by then, it had good balance and strong participants...but there were still, in people's minds, more than a century left to wrestle with consequences of their betrayals or follies.
It was also a time, where someone could be horrifically beaten around 1690 and quit, (which sometimes was best for everyone involved) and new blood could be injected, and they'd still have time to weave an entirely new identity for themselves.
HoI, and other games focused specifically on the Napeolonic Wars, just doesn't have that added element of risk vs reward or strategy.
